Early Game

***Early Game:
-For me it is MANDATORY that you maximize your [Ion Shell] on Dark Seer and abuse the Skill, place the Ion Shell to your creeps (preferably the melee-type and the one who isn't taking damage at the time.)

-Secondly I recommend utilizing your [Surge] because your enemies aren't that stupid to get close to the "infected" creep, when the "infected" creep is chasing that hero you can cast surge on it to basically... Chase that unlucky enemy.

-[Surge] is also an escape tool so that you can avoid any unnecessary attacks from enemy creeps, heroes and tower.

-Now you get to serious business, since you don't want to die and delay what is inevitable (completing your Radiance of course...) I suggest a little farming will help, support your allies by making a [Wall of Replica], then you [Vacuum] them in the middle of the wall, then you [Ion Shell] either yourself or your ally and you [Surge] either yourself or your ally (whoever is in the Ion Shell skill)... Then let your allies push while you farm your way to a [Radiance]

-Expecting a good game, you would've killed or assisted at least 9-14 players by now.
